Jerome Bruner
Background
Bruner’s early work on child development came at a time when thinking in
the area was dominated by the behaviourists. Behaviourism had developed
as a means of producing an objective and measurable way of explaining
the learning process, based, as it was, on scientific rigour. Bruner
was to apply similar techniques to the study of the internal mental
processes involved in learning and was therefore an early pioneer of the
cognitive approach to psychology. Bruner was heavily influenced by the
work of jean Piaget and later by the work of Lev Vygotsky. His eventual
theory shows the influence of both.
The child
According to Bruner, the child’s cognitive structures mature with age as
a result of which the child can think and organize material in
increasingly complex ways. Here we see influence of Piaget again, but
also of the information processing model. Children are also seen as
naturally inquisitive, thirsty for knowledge and understanding. The
child naturally adapts to its environment and abstract thinking develops
through action.
Constructivist theory
of cognitive development
Like Piaget and Vygotsky, Bruner believes the child has to learn for
itself by making sense of its own environment. In fact Bruner could be
seen as an ‘extreme constructivist’ since he believes the World we
experience is a product of our mind. What we perceive and think of as
our World is constructed through our mind as a product of symbolic
processes.
Bruner rejected the idea of stages as popularized by Piaget and to a
lesser extent Vygotsky. Rather than looking at the ages of
developmental changes Bruner concentrates more on how knowledge is
represented and organized as the child develops.
Modes of
representation
This looks as though its stages but it isn’t! With stages the child
would progress from one to the next and then, crucially, leave the old
way of thinking or operating behind. For Bruner, the earlier ways of
thinking are still used later in life where they can be very useful for
some tasks.
Modes of representation are the ways (or format) in which the child
manipulates information.
1. Enactive (First
year)
This is similar to the first half of Piaget’s sensori-motor stage of
development. The child has little in the way of mental faculties so
‘thinking is a physical action.’ Knowledge is what the child can
manipulate or do with movements, for example tying knots, pointing etc.
In later life the enactive mode will allow riding a bike, swimming,
driving a car and so on. These are automatic patterns of activity that
have been ‘hard wired’ into our muscles. Thinking about how we do them
or trying to explain to others in words how to tie shoe laces or ride a
bike is practically impossible because they are enactive. As for
Piaget, the gaining of object permanence is a major qualitative change
in the child’s thinking.
2. Iconic (Second
year)
This is similar to the second half of Piaget’s sensori-motor and
preoperational stages of development. For the first time the child has
mental images that allow it to retain pictures after the stimulus has
gone. Drawing is now possible. These icons or images are built up from
past experience and based on a number of exposures to similar objects
and events. Our image of a cup isn’t based soley on seeing one cup but
on seeing many. However, at present the child lacks the ability to
solve problems.
3. Symbolic (six or
seven years onwards)
This is similar to Piaget’s concrete operational stage of development.
For Bruner, symbols include words (language), music, numbers and so an.
Anything we use to symbolize something else. The precise timing of this
one depends on the child, particularly its language ability. For the
first time the child can categorise, think logically and solve problems.
Bruner’s main interest was in the child’s transition from iconic to
symbolic modes.
A
major implication of Bruner’s theory is that cognitive development can
be speeded up by training children in the use of symbols. Some of the
studies that follow (e.g. Frank) suggest that this is the case. Clearly
this runs counter to Piaget who believed progress through his stages was
biologically determined.
Culture provides the ‘instructions’ about how humans should develop and
these are passed on from one generation to the next. Bruner clearly
disagrees with Piaget’s view of the child as isolated and learning on
its own. The child works with others to develop its framework for
thinking and this framework is culture-dependent. Again we see the
influence of Vygotsky

Bruner and Kenney
(1966)
Aims- what age
children start to use symbolic mode of representation.
Method- children
aged 3-7 shown a board divided into 9 squares. On each square was a
plastic beaker. Beakers of different sizes & widths, tallest at back &
widest on left, each child had to look at the beakers. There was a
reproduction test were the beakers were mixed up and the child was asked
to put them back how they were.
Transposition test
removed beakers and asked them to put them back in a mirror image of the
original arrangement

Most 5 year olds
correctly completed the reproduction test however few under 7 could
complete the transposition task, most over 7 could complete both tasks.
The reproduction
task was designed to use iconic representation, as the child forms a
mental picture and copies it however the transposition task could not be
done as it doesn’t look like original arrangement.
Conclusion
The study supports
the view that children on average begin to acquire the symbolic mode at
around 6 or 7 years of age. The task required the ability to mentally
transform the visual information and was dependent on statements such as
‘it gets fatter going one way and taller going in another’ etc. The
children were using language (symbolic mode) to guide their thinking.
Brief biography |
Was born in
New York in 1915 and at time of writing is still going strong
(well still going) at the ripe old age of 94! Bruner had a
difficult childhood with early operations to correct his vision
and his father dying when he was only twelve. The rest of his
education was then interrupted by frequent changes of school.
Despite this however, Bruner studied at Duke University and went
on to get his PhD in psychology from Harvard University in
1941. Whilst there he met and worked under Gordon Allport, one
of the leading psychologists of his time.

Evidence for the
modes
Frank
(reported by Bruner 1964)
An ingenious
reworking of the classic Piaget water conservation study:
Frank selected a
group of 4 to 6 year olds that had been unable to successfully complete
the original Piaget test.
- They are shown the two measuring cylinders with equal amounts of water and the empty beaker.
- A screen is placed in front of the apparatus and a line drawn on the screen indicating the water level in the two taller cylinders.
- Water is poured from one of the cylinders into the beaker (all is still hidden behind the screen)
- The child is now asked ‘which has more to drink or are they both the same?’

- The screen is then removed and the child is again asked about which has the most water, the tall thin cylinder or the smaller but wider beaker
Results of this

4 year olds: revert
back to their original (incorrect answer) that the tall cylinder has
more water
5 and 6 year olds
generally stick to the correct answer given when the beakers were
hidden.
Explanation of
findings
In the Piaget
original, children can see the whole procedure and so rely on their
iconic mode to solve the task. By screening the procedure Frank was
preventing iconic mode and by asking them to describe what was happening
was encouraging their symbolic mode. This more advanced mode of
thinking was capable of conservation whereas the lower, iconic was not.
Later, when tested
without the screen, the older children were now able to conserve.
However, the younger children generally failed, even if they had been
able to do the task when it was screened. This suggests that lessons
had not been learned by this group and they had returned to iconic
thinking. Four year olds, it would seem, are mostly unable to acquire
symbolic thinking. This last finding appears to support Piaget’s idea
of preparedness. Regardless of methods used, some children are just too
young to progress further
Sonstroem et al
(1966)
In a similar
reworking of a Piagetian conservation task, children were asked to roll
out a ball of plasticine (enactive mode) so it was longer and thinner.
They were asked to watch their own actions (iconic mode) and to describe
what they were doing (symbolic mode). By using all three modes
together, the children were far more successful in conserving amount.
But: Although the
above researchers (and Bruner) put this improved performance down to the
use of language, other research Furth (1966) on deaf children, seems to
suggest that although language helps it isn’t essential for the
development of abstract thinking
Language
Here we have a major difference with Piaget but clear influence from
Vygotsky.
Let’s consider the transition from iconic mode to symbolic mode. For
Bruner this comes about through the mastering of language. Like
Vygotsky, Bruner thinks language accommodates cognitive development and
the two then become inextricably intertwined and over time develop side
by side each helping the development of the other. For Piaget language
is merely a tool that develops as a result of cognitive development.
Language is needed for communication with adults and older peers who can
facilitate learning. Similarly it is essential for the scaffolding
process.
Language of course is also essential for thought!
Bruner suggests language training as a way of speeding up the cognitive
development of the child, the concept of which would be totally alien to
Piaget.
Evaluation
The ability to acquire language is common across all human cultures.
This has led to the nativist theory of language acquisition, basically
that the rules for acquiring grammar are hard wired into the human
brain. Linguist, philosopher, political activist and all-round brain
box, Noam Chomsky suggested that humans possess a LAD (Language
Acquisition Device) that allows us to learn the rules of grammar when we
are exposed to human speech.
Bruner however, believes we possess a LASS* (Language Acquisition Social
System). Simply listening to language is not sufficient. The child
needs to be exposed to the mutual eye gazing and turn taking that are
needed for conversation. Language, according to Bruner, needs to take
place in a social context.
Evidence for this is provided by the case of Jim (and other deprived
children e.g. Genie).
Jim was born to parents that were both deaf and dumb. Until the age of
three, Jim’s only exposure to language was through the television.
Although he learned speech it was noticeably odd, with him developing
his own, unique grammatical characteristics and poor articulation (Sachs
et al 1981). Bruner suggests that this was due to lack of social
interaction in the learning of speech.
However, social interaction doesn’t explain all the complexities of
acquisition. The language we hear is often incorrect, poorly defined,
incomplete and full of hesitations, mispronounciations and other errors,
yet despite this we still learn to talk! It also takes place at a very
early stage in human development, when other cognitive skills are barely
beginning and when complex thought doesn’t exist.
Culture
According to Bruner our culture determines the sort of person we
become. There ‘cannot be a self independent of one’s culture.’
pplying Bruner to education
Unlike Piaget and Vygotsky, neither of whom tailored their work directly
towards education, Bruner seems to have had the education process in
mind throughout the formulation of his theory. 1960 saw the publication
of his ‘landmark’ text ‘The Process of Education’ in which he outlined
his idea that children, and learners in general, actively construct
their own knowledge.
As you would expect from a theory that has borrowed so much from the
work of Piaget and Vygotsky, Bruner’s ideas on education are very much
an amalgam of the two, and in particular the ideas of Vygotsky.
Basic philosophy
Bruner believes the child needs to grasp the basic principles of a
subject not simply acquire a list of facts. Once these are grasped, the
child is less reliant on others, and can go beyond what has been
formally taught, and progress to developing ideas of their own.
Throughout, it is important that the child learns for themselves
(influence of Piaget) but also that others, such as adults or more able
peers can assist in the learning process (influence of Vygotsky).
Unlike Piaget, Bruner believes that the process of cognitive development
can be speeded up with the aid of teachers and, like Vygotsky, believes
that scaffolding provided by the more competent is an essential part of
the teaching process. So teachers are seen as important, as is the role
of language and communication that facilitates scaffolding and language
use (symbolic mode) by the child.
Cooperative group work (similar to Vygotsky’s peer tutoring) is more
important that Piaget’s individual discovery learning. Evidence for
this is provided by Nichols:
Role of the teacher
Sutherland (1992) teachers are ‘obliged to make demands on their
pupils.’
Teachers are seen as essential in the Brunerian classroom. They need to
be aware of the child’s mode(s) of representation, provide scaffolding
and speed up development. See below for more detail on each of these:
Nichols (1996)
Studied 81 high school students across an 18 week term.
The students were split into 3 groups:
Group 1: 18 weeks of traditional teaching
Group 2: 9 weeks of cooperative group learning followed by 9 weeks of
traditional teaching
Group 3: 9 weeks of traditional teaching followed by 9 weeks of
cooperative group teaching
The cooperative method involved splitting the 27 students into small
groups where they worked together on solving geometry problems.
Motivation of the students was measured before the study, after 9 weeks
and 18 weeks
Results
Cooperative group teaching significantly improved motivation with the
biggest increase being during the 9 week phase of the co-op teaching.
Conclusion
Cooperative group teaching is good for improving the motivation of
students which would seem to support the effectiveness of student-centred
learning, the approach favoured by both Bruner and Vygotsky.
Speeding up cognitive
development
Teachers, according to Bruner, should be able to speed up the rate of
cognitive development, primarily by improving language acquisition,
assisting the transition form iconic to symbolic modes of
representation. According to Bruner, the provision of stimulation by
teachers should also increase development, particularly in those from
deprived backgrounds. The thinking here is that those from poorer
backgrounds receive less mental stimulation in their home environment so
benefit more when it is provided during the education process. Evidence
suggests that children from deprived backgrounds receive less one to one
attention from parents and fewer stimulating toys. In the UK the
introduction of the National Curriculum in the 1980s was designed to
improve attainment across all groups but particularly those in the
bottom 40%. Teachers have since been expected to increase the rate of
cognitive development.
CASE
CASE (Cognitive Acceleration through Science Education) was designed
with this in mind. Shayer and Adey that devised the program claim
success, particularly in boys but only when the program is administered
in year 8. When year 7s follow the program they show little
improvement. Here we have support for i. Bruner: development can be
speeded up, but also for ii. Piaget. Children below year 8 simply are
not ready for the progression from concrete to formal thinking
regardless of the support given.
The Spiral Curriculum
This refers to that very annoying habit that teachers have, of
constantly returning to topics each year, but teaching them in different
ways! You were probably taught ‘electricity’ in years 3, 5, 7, 9 and 11
and each time your new science teacher would say next week we’re going
start ‘electricity’ you would doubtless have moaned since you’d done it
before. However, as you’d realize if you thought back, each time you
would have been taught the topic differently, in ever more complex and
eventually in more abstract ways.
Unlike Piaget and his concept of ‘readiness’ that suggests we should
only teach abstract concepts when the child has the mental apparatus to
cope, Bruner believes any topic can be taught in a meaningful and
helpful manner to any child. Take the example of ‘volume.’
- Baby: let it play with a bucket and some water (perhaps at the beach)
- Pre-school: again play with buckets but this time introducing basic vocabulary such as ‘bucket’, ‘more’ and ‘less.’
- Junior school: Now introduce more complex terminology such as ‘volume’ and ‘conservation.’
- Secondary school: introduction of abstract concepts such as formulae and the removal of concrete examples.
Modes of
Representation
In terms of education the influence of the modes is similar to Piaget’s
stages, in that the teacher needs to be aware of the mode(s) being used
by each child and structure their teaching, resources and activities
around these modes. So for example, early teaching will centre on the
enactive mode so activities will need to be hands on and practical in
nature.
Taking teaching about dinosaurs as an example: this could involve making
models (enactive), watching the BBC’s ‘Walking with dinosaurs (iconic)
or an internet search for information (symbolic).
Computers
Computers are very useful in the Brunerian classroom since they can
provide scaffolding. Software on a number of educational programs
provide prompts and also a range of ‘help’ menus and facilities so the
amount of scaffolding provided can be varied to suit the needs of the
developing child. Children can also work on group tasks using computers
facilitating social interaction with all the Brunerian benefits that go
with that (cooperative learning, language etc).
Computers, as any teacher will tell you, also keeps students busy. This
allows the teacher to hover and observe, provide scaffolding when
required and intervene and target students that are struggling with
additional assistance.
